Abstract
The utility model relates to a double-block monospar rail framed bent for construction of a ballast-free monolithic ballast bed of a high-speed railway. The double-block monospar rail framed bent is formed by fixedly connecting two parallel tool rails with bridles, two ends of the bridles are fixed with framed bent stud outriggers and rail-direction locks. The double-block monospar framed bent improves measuring control accuracy and construction quality of the ballast bed through stable matching performance and high measuring accuracy and by taking measures of matching construction process, quality detection standards, correct measuring methods and scientific data processing methods. Detection of control, replacement and pavement of long rails, stress relieving and line locking during construction indicates that the structural position of the rails meet the requirements of standard test and control purposes of 'high smoothness and high accuracy' are achieved. The double-block monospar rail framed bent has the advantages that construction quality is conveniently controlled, operation efficiency is improved, and programming, standardization operation and management are facilitated by the aid of ballast-free rail control concepts and measures, the railway framed bent assembly technology, the railway accuracy control technology and the ballast bed concrete casting process.
